“We” want to go to Mars, and it will happen. But I wonder why we would want that.
The shortest distance to Mars is about 60 million kilometres. With our current technology it takes about 9 months to reach the planet.
A lot of people, like Elon Musk, have started to justify going to Mars as an important stepping stone to explore the rest of the universe in any coming future.
We have to do that, because in about 5 billion years (give or take a couple of billion), the sun will explode and our whole solar system will cease to exist. Including Mars.
So Mars is not an option in itself to let Mankind survive.
The next closest opportunity we might be able to live on is super-earth GJ357 d (in the solar system of star GJ 357). That’s only 31 light-years away.
Or in comprehensible terms 31* 9500 billion kilometres.
In this perspective the jump to the Moon is just as useful as the crazy endeavour to Mars.
Okay, in my opinion reaching GJ357 is feasible, but not as humans as we are now. We will have to be cyborgs by then.
Is that what we want to have survived? What we want to be our legacy as Humans to the universe?!
I think we want to go to Mars, because we just want to. The rest of the motivations are, hmmm, I would say at least “naive”.
My CSPE is: why in whose ever name do we want to go to Mars?
